Package Management - RedHat Systems

RedHat-based systems, such as Fedora and CentOS, use a different package management system than Debian-based systems. Instead of APT, they use the Yellowdog Updater Modified (YUM) or Dandified YUM (DNF) package manager.

YUM

YUM is the package manager used in RedHat 5 and 6. To install a package using YUM, you would use the following command:

yum install package-name 

To remove a package using YUM, you would use the following command:

yum remove package-name 

DNF

DNF is the default package manager in newer versions of RedHat, including Fedora and CentOS 8. It is a successor to YUM and provides better performance and improved dependency resolution.

To install a package using DNF, you would use the following command:

dnf install package-name 

To remove a package using DNF, you would use the following command:

dnf remove package-name 

RPM

In addition to YUM and DNF, RedHat-based systems also use the RPM package format. RPM stands for Red Hat Package Manager and is a low-level package management tool that is used by both YUM and DNF.

To install an RPM package, you would use the following command:

rpm -i package-name.rpm 

To remove an RPM package, you would use the following command:

rpm -e package-name.rpm 

Conclusion

In this section, we learned about the package management systems used in RedHat-based systems. We covered YUM, DNF, and RPM, and saw how to install and remove packages using each of these tools. Understanding package management is an important skill for any Linux administrator, and knowing how to use both APT and YUM/DNF is crucial for working with both Debian-based and RedHat-based systems.
